Protein Lactylation Is Induced in the Brain by Neural Activation and Social Stress

In mice, protein lactylation occurs in neurons and is correlated with lactate levels. Protein lactylation is enhanced by neural excitation and social stress. Researchers found social stress specifically enhances lysine lactylation of histone H1 proteins.

Why stress doesn’t always cause depression

Rats susceptible to anhedonia have more serotonin neurons in the ventral dorsal raphe nucleus. However, activating neurons in the central amygdala reduced the serotonin signaling and lowered the effects of social stress.

Dogs mirror owner’s stress

Researchers identify an interspecies correlation between hair cortisol concentrations in humans and dogs during summer and winter months. The cortisol levels were not affected by the amount of activity the dog had during these periods. The study reveals a seasonal effect in higher cortisol levels between humans and animals, and human personality traits significantly affected the dog's level of stress. Findings suggest that dogs often mirror the stress levels of their owners.

How stressed-out gut bacteria may trigger autoimmune response

Chronic social stress in mice induces the expression of virulent genes in the gut microbiota. The altered microbiota increases the presence of effector T helper cells in the lymph nodes and induces myelin autoreactive cells. Exposure to chronic stress, therefore, may increase the risk of developing autoimmune diseases for some individuals with a susceptibility.
